The results of the study on the comparative assessment of different tillage methods in the field crop rotation with different levels of mineral nutrition (N30P30 and N60P30 kg of active ingredient/ ha) are presented. The experiment was carried out on low-humus low-carbonate chernozem of the forest-steppe zone of Eastern Trans-Baikal Territory in 2012–2014. The zoned variety of Buryatskaya-79 spring wheat, and Metis oat variety were used for sowing. Low-cost methods of soil tillage were studied, providing for the preservation and improvement of soil fertility, an increase in the productivity of grain and fodder crops, and a decrease in material and energy costs. Replacement of the basic tillage with a PN-4-35 plow with a ring roller in the third and fourth crop rotation fields by surface tillage with a Stepnyak-7.4 cultivator and direct sowing on the stubble with a PPM Ob4-ZT seeder when applying mineral fertilizers at a rate of N60P30 kg of active ingredient/ha had a positive effect on the condition of the soil. The following indicators of soil fertility were achieved: structural coefficient 1.28–1.38, organic matter content 3.15–3.33%, productive moisture content in the 0–50 cm layer 29.2–31.8 mm, the release of carbon dioxide 1.810–1.969 kg per 1 hour, the content of Р2О5 in the 0–20 cm layer 71–96 mg/kg of soil, the content of K2O – 57–82 mg/kg of soil. An increase in the yield of oat grain of 0.16–0.21 t/ha, the green mass of annual grasses of 3.44.0 t/ha, the collection of feed units of 0.32–0.34 t/ha, a reduction in the cost of fuel and lubricants by 31.2-36.4%, and an increase in profitability by 25.0–40.3% were achieved.

The Impact

The problem statement. For the last two decades in Ukraine a fast decrease in chornozemic soil fertility, especially a decline of its agrochemical properties, has been noticed. One of the way of improvement its fertility is to develop and implement scientifically-based resource-saving and soil-protective system of tillage operations along with rational fertilization of field crops on the tilled soil. The aim of the research – with the help of a field experiment to define a rational system of main tillage and fertilization of typical chornozemic soil under a grain row five course rotation which provides 5,5 t/ha of dry matter from a tilled field under the expanded reproduction of agrochemical indices of soil fertility and appropriate energetic efficiency. Conclusions. Under disc and beardless tillage especially of fertilized areas a differentiation of tilled soil layer according to the agrochemical indices of its fertility is observed. A stabilization of humus and general nitrogen content as well as fertilizer elements in a tilled soil layer occurs under application of 8 t/ha of pus + N76P64K57. The efficiency of humification processes in soil is the lowest under disc tillage and the highest under beard-beardless and beard tillage in a crop rotation. Along with the increase of soil depth of its tilled layer, annual decrease of its general nitrogen supply on the untilled areas under beard and differential tillage falls down. However, under beardless and disc tillage it increases. An inverse relation is observed on the untilled areas. Under beard and beard-beardless tillage almost the same crop rotation productivity was obtained, while under beardless and disc tillage the productivity was significantly lower. For a field grain row five course crop rotation of Right Bank Forest-steppe of Ukraine a deep arable tillage is recommended only in one filed, and in the rest fields beardless and disc tillage with the application of 8 tones of pus per hectare of tilled field + N76P64K57 under a common reproduction and 12 t/ha of pus + N95P82K57 under expanded reproduction of typical chornozemic soil fertility is recommended. Key words: soil, tillage, crop rotation, fertilizers, fertility, rotation.

Complex studies were conducted in eight-field grain-steam-crop and grain-steam-tilled crop rotations using the following terms: fertilizer systems, plant protection, basic tillage methods and plastic varieties. Scientific novelty lies in the fact that for the first time in the forest-steppe of the Volga region, on a systemic basis, resource-saving technologies have been developed on the basis of fertile crop rotations in an ecologically balanced, biologized farming system. Agroecological principles of conservation and reproduction of gray forest soil fertility and obtaining a planned harvest of high quality. Experimental substantiation of the role of action and interaction of the main factors of saving technology, in increasing crop productivity of crop rotations, productivity of arable land and soil fertility. Agroeconomic evaluation of the resource-saving technology effectiveness. Crop rotations of leguminous crops and perennial legumes increase the productivity of arable land to 15-20%, provide a positive balance of humus (0.45-0.5 tons per hectare). Organomineralic fertilizer system reduces the need for mineral fertilizers by 2-3 times, ensures the receipt of planned high quality harvest and reproduction of soil fertility. The integrated plant protection system, using biological means and methods, provides a saving of plant protection products to 30-35%, raises productivity to 15-25%. Moisture-resource-saving mode of soil cultivation (mulching various deep loosening without turnover of beds) allows to save 25-35% of fuel and reduce the moisture loss to 35-40%. Complex application of these factors with the use of high-yielding plastic varieties makes resource-saving technology that increases the productivity of cultivated crops and the productivity of arable land by 1.5-2 times, the profitability of production by 30-50% and ensuring the reproduction of soil fertility.

The Impact

The article presents the results of studies conducted in 2004-2010 at the experimental plot in the forest-steppe Volga region. The research investigated the impact of traditional (average) and differentiated use of mineral fertilizers in the field crop rotation (winter wheat (reconnaissance sowing) – spring wheat ‒ annual grass – spring barley – bare fallow– winter wheat – spring wheat) on the change of agrochemical properties of leached chernozem. It was established that the six-year use of fertilizers contributed to the improvement of the main indicators of top soil fertility regardless of application technology. On average, in 15 sectors (plots) of each variant, the content of mobile phosphorus per rotation of crop rotation increased with differentiated fertilization by 15.9%, potassium – by 15%, and in the traditional one – by 4.8 and 16.7% respectively, (control of 100.8 and 116.2 mg/kg of soil, respectively). In sectors where no fertilizer was applied, the content of mobile elements decreased by 2-7%. The nitrogen content in the soil directly depended on the timing of sampling and the amount of moisture in the soil, so it was difficult to track its change. The difference in the accumulation of mineral nitrogen between the technologies of fertilizer application was not observed. For organic matter in all variants of the experience over the years of research there was a decrease in the indicator. This was more noticeable in the control, where the value decreased by 2.7%. Here, the value of soil acidity increased by 0.12 units and became 4.7. In variants with fertilizers soil acidity remained the same (4.6-4.7). In general, the differentiated use of mineral fertilizers did not have a negative influence on the agrochemical composition of leached chernozem. There was a gradual equalization of soil fertility due to the residual amounts of phosphorus and potassium on low-fertile plots and some reduction of mobile elements in zones with high content.

The paper presents the results of stationary multifactor field experiment on study of the mutual impact of various systems of soil deep and surface tillage in combination with various levels of organic and mineral fertilizers application on crop rotation performance, as well as on a number of agrochemical indicators of black soil fertility. Researches were carried out as a stationary field experiment on the experimental field of Bila Tserkva National Agrarian University in 2013-2018. During the crop rotation in all the studied tillage methods, especially mouldboardless and disking tillage, the hydrolytic acidity of the arable layer increased with increase in fertilizer rates, and the amount of bases absorbed, saturation degree, level of exchangeable calcium and magnesium cations decreased, but in most cases these changes were not significant. Systematic mouldboardless and disking tillage enhance the topsoil heterogeneity in relation to agrochemical indicators of its fertility. Heterogeneity increases with increase in the level of applied fertilizers. With the mouldboard tillage during the crop rotation period at unfertilized areas, the largest part of humus loss in the arable layer is observed in the top, and the smallest - in its bottom parts; the opposite pattern was observed on fertilized areas at the highest rate. With mouldboardless and disking tillage, directly opposite patterns were observed in comparison with mouldboard tillage. An annual application of 8 t/ha of manure + N76P64K57 stabilizes the humus state of the arable soil layer when carrying out differentiated and disking tillage in crop rotation. Fertilization rate of 12 t/ha of manure + N95P82K75 for these tillage options a significant increase in humus and total nitrogen reserves is provided.

Different Doses

The productivity of agricultural crops is the most variable and integral indicator of their vital activity, which accumulates their genetic potential, soil fertility, weather conditions and components of agricultural technology. Soybean under optimal growing conditions (the reaction of the soil is close to neutral, sufficient phosphorus and potassium nutrition, the use of nitraginization) assimilates from the air about 70 % of the total nitrogen requirement. Therefore, it is believed that it is enough to apply only a starting dose of nitrogen fertilizers (20–40 kg/ha a. s.), to get a high yield with good indicators of grain quality. The results of studies of the influence of long-term (8 years) application of different doses and ratios of fertilizers in field crop rotation on podzolized chernozem in the conditions of the Right -Bank Forest-Steppe of Ukraine on the yield and quality of soybean seeds preceded by spring barley were presented. It was found that crop yields could be increased by 18–77 % owing to different doses, ratios and types of fertilizers. The highest indicators of seed yields for three years of the research (3,02 t/ha) were obtained under the application of mineral fertilizers at a dose of N110P60K80 per 1 ha of crop rotation area, including under soybean – N60P60K60. Exclusion of the nitrogen component from the complete fertilizer (N60P60K60) reduced its yield by 26 %, phosphorus – by 17, and potassium by 11 %. There was no significant decrease in soybean yield in the variant of the experiment with a decrease in the proportion of potassium in the composition of complete mineral fertilizer (N60P60K30) for three years of study. The largest mass of 1000 soybean seeds was formed at doses of N60К60 fertilizers, and their protein content — under the application of complete mineral fertilizer in doses of N60P60K60 and N60P60K30.

Farmland Soil

Soil nutrients are essential nutrients provided by soil for plant growth. Most researchers focus on the coupling effect of nutrients with potato yield and quality. There are few studies on the evaluation of soil nutrients in potato fields. The purpose of this study is to investigate the soil nutrients of potato farmland and the soil vertical nutrient distributions, and then to provide a theoretical and experimental basis for the fertilizer management practices for potatoes in Loess Plateau. Eight physical and chemical soil indexes were selected in the study area, and 810 farmland soil samples from the potato agriculture product areas were analyzed in Northern Shaanxi. The paper established the minimum data set (MDS) for the quality diagnosis of the cultivated layer for farmland by principal component analysis (PCA), respectively, and furthermore, analyzed the soil nutrient characteristics of the cultivated layer adopted soil quality index (SQI). The results showed that the MDS on soil quality diagnosis of the cultivated layer for farmland soil included such indicators as the soil organic matter content, soil available potassium content, and soil available phosphorus content. The comprehensive index value of the soil quality was between 0.064 and 0.302. The SPSS average clustering process used to classify SQI was divided into three grades: class I (36.2%) was defined as suitable soil fertility (SQI < 0.122), class II (55.6%) was defined as moderate soil fertility (0.122 < SQI < 0.18), and class III (8.2%) was defined as poor soil fertility (SQI > 0.186). The comprehensive quality of the potato farmland soils was generally low. The proportion of soil nutrients in the SQI composition ranged from large to small as the soil available potassium content = soil available phosphorus content > soil organic matter content, which became the limiting factor of the soil organic matter content in this area. This study revolves around the 0 to 60 cm soil layer; the soil fertility decreased gradually with the soil depth, and had significant differences between the respective soil layers. In order to improve the soil nutrient accumulation and potato yield in potato farmland in northern Shaanxi, it is suggested to increase the fertilization depth (20 to 40 cm) and further study the ratio of nitrogen, phosphorus, and potassium fertilizer.

The paper presents the main results of the monitoring on the effectiveness of the cross-compliance Standard 4.1 ‘Permanent pasture protection: lett. b, c’ carried out in two case studies within the project MO.NA.CO. Soil, botanical, productive and economic (competitiveness gap) parameters have been monitored. In the short term, the Standard 4.1 showed its effectiveness on soil quality, biomass productivity and competitiveness gap in both case studies. Botanical parameters showed differing results, therefore their generalization is not applicable to the heterogeneity of the pasture land Italian system. Shallow soil tillage could be suggested, every 40-50 years, when an appropriate soil organic matter content and the absence of runoff phenomena occur.
